Abstract
The purpose of this work is to study one dc reactor type three-phase current Iimiter(FCL) using high temperature superconducting(HTS) coil, connected with the secondary winding of a transformer through a diode bridge. HTS provides the advantages of a higher temperature operation, preferably applied to the dc reactor type FCL, where a superconducting coil can be operated at lower voltage and dc current. We propose one dc reactor type three-phase FCL incorporating only one HTS coil and present its test result. One reactor type three-phase FCL for 6.6 kV-2000 A is compared with the three reactors type from the point of view of a current limitation and the required HTS coil.
